"I have experienced engine cut

"I have experienced engine cutout, after several RPM drop offs, and I suspected the culprit may be the circuit breaker. I am not sure, but the left engine would run at high speed &#40;3200 rpm&#41; for a while and then the rpm would suddenly drop, rise back to the set rpm and then shortly after it would begin to drop and cut the engine off. After a short time I could restart the engine and it would run for a short while then it would stop again. Then I ran both engines, on the way back at 1500 rpm, until the left cut out again, and after it I could not restart the engine anymore. Do I have a problem with this circuit breaker or something else.
Please let me know.
Thanks,
Gene"

"I pulled hair out for months

"I pulled hair out for months chasing what wound up being an intermittent open circuit, &#40;a broken wire, just barely making connection, most of the time&#41; at the factory crimped connector, in a distributor.

Always restarted after 5 seconds - 5 minutes, and acted like a fuel or ing. coil problem. but never like shutting the key off once up to planing speed.

The OP and Temp gauges will do

"I'm having a similar prob

"I&#39;m having a similar problem. The main circuit breaker repeatedly was popping. The faster I go, the faster it pops. After waiting, I can reset it. The breaker had some corrosion on the leads so I replaced it yesterday. The Cobalt dealer didn&#39;t know what the amperage is, I can&#39;t find it in my shop manual or owners manual, Cobalt doesn&#39;t reply to emails, and it doesn&#39;t appear on the breaker. We guessed at 20 amps. After installing it, it has run great for 2 hours. I&#39;m seeing some references to 15 amp fuses in comments about similar boats. Does anyone know what amperage goes with these Mercruiser based dash setups? I don&#39;t want to overload the system by having too large a breaker. I have an 1987 Cobalt 17BR with 4.3L V6."
